B Vitamins

The B vitamins are a group of water-soluble vitamins that play important roles in cell metabolism. The B vitamins were once thought to be a single vitamin, referred to as vitamin B (much as people refer to vitamin C or vitamin D). Later research showed that they are chemically distinct vitamins that often coexist in the same foods. In general, supplements containing all eight are referred to as a vitamin B complex. Individual B vitamin supplements are referred to by the specific name of each vitamin (e.g., B1, B2, B3 etc.).

List of B vitamins :

Vitamin B1 (thiamine)
Vitamin B2 (riboflavin)
Vitamin B3 (niacin or niacinamide)
Vitamin B5 (pantothenic acid)
Vitamin B6 (pyridoxine, pyridoxal, or pyridoxamine, or pyridoxine hydrochloride)
Vitamin B7 (biotin)
Vitamin B9 (folic acid)
Vitamin B12 (various cobalamins; commonly cyanocobalamin in vitamin supplements)

Health benefits

The B vitamins may be necessary in order to:

Support and increase the rate of metabolism
Maintain healthy skin and muscle tone
Enhance immune and nervous system function
Promote cell growth and division, including that of the red blood cells that help prevent anemia
Reduce the risk of pancreatic cancer - one of the most lethal forms of cancer - when consumed in food, but not when ingested in vitamin tablet form.

All B vitamins are water-soluble, and are dispersed throughout the body. Most of the B vitamins must be replenished regularly, since any excess is excreted in the urine.

B vitamin sources

B vitamins are found in whole unprocessed foods. Processed carbohydrates such as sugar and white flour tend to have lower B vitamin than their unprocessed counterparts. B vitamins are particularly concentrated in meat such as turkey and tuna, in liver and meat products. Good sources for B vitamins include kombucha, whole grains, potatoes, bananas, lentils, chili peppers, tempeh, beans, nutritional yeast, brewer's yeast, and molasses. Although the yeast used to make beer results in beeramin B9 (folic acid) deficiency in early embryo development has been linked to neural tube defects. Thus, women planning to become pregnant are usually encouraged to increase daily dietary folic acid intake and/or take a supplement. However, for "most typical consumers of energy supplements or
drinks, B vitamins are nothing more than a 'gimmick'.

Related nutrients

Many of the following substances have been referred to as vitamins because they were believed to be vitamins at one time. They are not considered vitamins any more and the numbers that were assigned to them now form the "gaps" in the true series of B-complex vitamins described above (e.g. there is no vitamin B4). Some of them, though not essential to humans, are essential in the diets of other organisms; others have no known nutritional value and may even be toxic under certain conditions.

Vitamin B4: adenine, a nucleobase, is synthesized by the human body.

Vitamin B8: adenosine monophosphate, or alternately myo-inositol, is synthesized by the human body.

Vitamin B9: Folic Acid is also known as "vitamin I" of Centanni E. (1935)—also called "Enteral factor"—is a water and alcohol-soluble rice-bran factor that prevents digestive disturbance in pigeons. It governs the anatomical and functional integrity of the intestinal tract. Later found in yeast. Possible candidates for this substance are inositol, niacin (nicotinic acid), and biotin. Carnitine was also claimed to be a candidate but is not soluble in alcohol.

Vitamin B10: para-aminobenzoic acid (PABA)

Vitamin B11: pteryl-hepta-glutamic acid—chick growth factor, which is a form of folic acid. Later found to be one of five folates necessary for humans; also known as vitamin S or factor S. L-Carnitine is called

vitamin B11 in France.

Vitamin B13: orotic acid, now known not to be a vitamin.

Vitamin B14: cell proliferant, anti-anemia, rat growth, and antitumor pterin phosphate named by Earl R. Norris. Isolated from human urine at 0.33ppm (later in blood), but later abandoned by him as further evidence did not confirm this. He also claimed this was not xanthopterin.

Vitamin B15: pangamic acid

Vitamin B16: dimethylglycine (DMG)

Vitamin B17: nitrilosides, amygdalin or Laetrile. These substances are found in a number of seeds, sprouts, beans, tubers, and grains. While toxic in large quantities, proponents claim that it is effective in cancer treatment and prevention despite a lack of accepted scientific evidence.

Vitamin B18:

Vitamin B19:

Vitamin B20: carnitine

Vitamin B21:

Vitamin B22: often claimed as an ingredient of Aloe vera extracts but also in many other foods. Claimed by one source to be vitamin B12b-δ.

Vitamin Bh: biotin

Vitamin Bm: "mouse factor": also used to designate inositol

Vitamin Bp: choline Choline is only required for survival of some mutants. Most commonly it is synthesized in vivo de novo. May be added as supplement especially when methionine supply is limited

Vitamin Bt: L-carnitine

Vitamin Bv: a type of B6 but not pyridoxine

Vitamin Bw: a type of biotin but not d-biotin

Vitamin Bx: para-aminobenzoic acid

Note: B16, B17, B18, B19, B20, B21 & B22 do not appear to be animal factors but are claimed by some naturopaths as human therapeutic factors.
